How to fix ALA02 alarm on Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner displays an ALA02 alarm indicating that Probe B2 is faulty or disconnected, it could be due to sensor failure or the sensor not being correctly connected. Check the connection on the motherboard or replace the sensor.
What to do for EEV motor error alarm ALD03 on Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner is showing an EEV motor error alarm (ALD03), it may be caused by incorrect or missing wiring between the motherboard and the valve motor. Check the connection on the motherboard or replace the valve motor.
What does Power+ offline alarm ALL01 mean on Rittal LCP Rack DX 12?
If your Rittal Air Conditioner displays a Power+ offline alarm (ALL01), it indicates wrong communication between the driver and the motherboard. Check the MODbus connection cable and the communication parameters.
What causes an unexpected inverter stop error 99 on Rittal LCP Rack DX 12?
If your Rittal Air Conditioner experiences an unexpected inverter stop (error 99), it could be due to a short power failure. Restart the unit. If necessary, connect it to a UPS.
Why is my Rittal Air Conditioner showing a high pressure alarm ALB01?
If you are encountering a high-pressure alarm (ALB01) on your Rittal Air Conditioner, it could be due to a high ambient temperature, incorrect coolant filling, or a defective fan. To resolve this, check the device limits, verify the coolant volume, and ensure the fan is functioning correctly.
Why am I getting a max temperature warning ALW04 on my Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner shows a max temperature warning (ALW04), it could be because a previous alarm has stopped the unit, or the heat load is too high compared to the cooling capacity of the unit. Reset the previous alarm to resolve this.
What does the envelope alarm zone ALC03 mean on a Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner displays an envelope alarm zone (ALC03), it indicates that the operating conditions are outside of the compressor specifications. Check the operating conditions as per compressor specifications.
What does Rittal Air Conditioner Power+ Generic Alarm ALL02 mean?
If your Rittal Air Conditioner shows a Power+ Generic Alarm (ALL02), it could be caused by over or under current, over or under voltage, or over or under temperature of the drive of the compressor motor. Check the cable and any previous high-pressure alarm. Refer to the drive manual "code [105]" for more information.
What causes a high evaporation temperature alarm (ALD07) on a Rittal Air Conditioner?
If your Rittal Air Conditioner is showing a high evaporation temperature alarm (ALD07), it could be due to a high inlet temperature or an incorrect PID valve parameter. Check the valve PID parameters and the alarm delay. If the condenser ambient temperature is at most 35°C, raise the MOP limit (max. 25°C).
